Technical Field
[0001] This utility model relates to the field of industrial control technology, specifically a high-temperature resistant industrial-grade switch. Background Technology
[0002] Industrial-grade switches are key network devices used for data transmission and device interconnection in industrial control systems. They are widely used in complex industrial environments such as smart manufacturing, petrochemicals, and power transmission. In these scenarios, devices often need to operate under harsh conditions such as high temperature, dust, and vibration for extended periods. Stable network communication is a core prerequisite for ensuring smooth production processes, accurate data acquisition, and effective remote monitoring. Therefore, industrial-grade switches with high-temperature resistance have become an important support for ensuring the continuous and reliable operation of industrial systems. They can maintain stable data processing and transmission capabilities in high-temperature environments, avoiding communication interruptions or failures caused by overheating.
[0003] Traditional industrial-grade switches have significant limitations in high-temperature resistance design. Most traditional products rely solely on simple metal casings or small ventilation holes for heat dissipation and temperature regulation. When the ambient temperature exceeds their tolerance threshold, internal components are prone to performance degradation due to heat accumulation, resulting in increased data transmission latency and packet loss rates. In severe cases, this can even lead to equipment shutdown. This not only interrupts real-time data interaction in industrial production, affecting production efficiency, but may also prevent timely detection of system anomalies due to interruptions in critical monitoring data transmission, leading to more serious consequences such as equipment damage and production accidents. It is difficult to meet the requirements of long-term stable operation of equipment in high-temperature industrial environments. Therefore, we propose a high-temperature resistant industrial-grade switch. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a high-temperature resistant industrial-grade switch, which solves the aforementioned problems.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a high-temperature resistant industrial-grade switch, comprising: The switch housing and the switch frame are provided. The interior of the switch housing is hollow. The bottom of the hollow interior of the switch housing is fixedly connected to the switch frame by a connecting rod. The switch frame is provided with a switch structure, which is linearly distributed longitudinally inside the switch frame. A heat dissipation structure is provided on the top of the switch housing, and the heat dissipation structure is distributed axially symmetrically on the top of the switch housing; An auxiliary structure is disposed on the side of the switch rack, and the auxiliary structure is distributed symmetrically on both sides of the switch rack; The cooling structure is located at the bottom of the switch housing, with one end of the cooling structure entering the hollow interior of the switch housing and the side fixedly connected to the auxiliary structure.
[0006] Preferably, the side of the switch housing has two sets of longitudinally linearly distributed ventilation slots, which penetrate the side wall of the switch housing and are symmetrically distributed at both ends of the side wall of the switch housing.
[0007] Preferably, the outer side of the switch housing is hinged with a side door that seals the side of the switch housing. A display screen is fixedly installed on the outer side of the side door near the top. The heat dissipation structure includes a heat dissipation fan mounting slot and a heat dissipation fan. A set of symmetrical heat dissipation fan mounting slots is provided on the top of the switch housing. The heat dissipation fan mounting slots penetrate the top of the switch housing. A heat dissipation fan is fixedly installed in the heat dissipation fan mounting slot. The switch frame is located directly below the heat dissipation fan.
[0008] Preferably, the auxiliary structure includes a switch placement platform, a heat dissipation groove, and a support rod, and the switch rack has longitudinally linearly distributed switch placement platforms on its side.
[0009] Preferably, the side of the switch rack is provided with heat dissipation slots, the position and number of which correspond to the switch placement platform, and the heat dissipation slots penetrate through the side wall of the switch rack. Multiple sets of horizontally linearly distributed support rods are fixedly installed between adjacent heat dissipation slots on the outside of the switch rack.
[0010] Preferably, the switch structure includes a switch and connection ports. The switch is fixedly installed inside the switch platform, and multiple sets of connection ports are opened on the outer wall of the switch on one side in a horizontally linear distribution.
[0011] Preferably, the cooling structure includes mounting holes, a coolant tank, a cooling pipe fixing plate, and cooling pipes. The coolant tank is fixedly installed at the bottom of the switch housing. A set of through mounting holes is provided at the bottom of the switch housing. The cooling pipe fixing plate is fixedly connected to the side of the support rod. The cooling pipe is fixedly installed on the outside of the cooling pipe fixing plate. The bottom of the cooling pipe passes through the mounting hole and enters the coolant tank.
[0012] Compared with the prior art, this utility model provides a high-temperature resistant industrial-grade switch, which has the following beneficial effects: 1. This high-temperature resistant industrial-grade switch achieves efficient cooling through a composite design of "active air cooling + passive liquid cooling + structural auxiliary heat dissipation." Symmetrically distributed cooling fans at the top directly force airflow into the switch rack, while the coolant tank at the bottom dissipates heat through cooling pipes. These, along with the heat dissipation grooves on the sides of the switch rack and corresponding to the placement platform, form a three-dimensional heat dissipation channel. Simultaneously, ventilation slots on the outer shell accelerate air convection. The longitudinally linearly distributed switch placement platform ensures the switch structure is orderly separated within the switch rack, reducing thermal interference between components. The symmetrical auxiliary structures on both sides feature support rods that enhance the overall frame stability and provide fixed supports for the cooling pipes, preventing component loosening under vibration. Furthermore, the hinged side door design allows for direct access for maintenance without disassembling the outer shell, and the display screen provides real-time monitoring of the equipment status. Components such as cooling fan mounting slots and cooling pipe fixing plates can be adjusted in number and position according to actual temperature requirements. For example, in extreme high-temperature environments, the number of cooling fans can be increased or the cooling pipe layout optimized. Additionally, the linear distribution design of the switch placement platform supports flexible combinations of multiple switch structures to meet the data transmission needs of industrial networks of different sizes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 A high-temperature resistant industrial-grade switch, comprising: The switch housing 1 and the switch rack 9 are hollow inside. The bottom of the hollow interior of the switch housing 1 is fixedly connected to the switch rack 9 by a connecting rod. The switch rack 9 has a switch structure inside, and the switch structure is linearly distributed longitudinally inside the switch rack 9. The heat dissipation structure is located on the top of the switch housing 1, and the heat dissipation structure is distributed symmetrically on the top of the switch housing 1. The auxiliary structures are located on the sides of the switch rack 9 and are symmetrically distributed on both sides of the switch rack 9. The cooling structure is located at the bottom of the switch housing 1. The other end of the cooling structure enters the hollow interior of the switch housing 1 and is fixedly connected to the auxiliary structure on the side.
[0017] Furthermore, two sets of longitudinally linearly distributed ventilation slots 2 are provided on the side of the switch housing 1. The ventilation slots 2 penetrate the side wall of the switch housing 1 and are symmetrically distributed at both ends of the side wall of the switch housing 1. The two sets of longitudinally linearly distributed ventilation slots 2 on the side of the switch housing 1 can not only form air convection with the top cooling fan 6, but also slowly dissipate the heat retained inside the switch housing 1 through natural ventilation when the equipment is not running or under low load, avoiding long-term heat accumulation inside the housing. At the same time, its symmetrical distribution design can ensure uniform airflow on both sides of the housing, preventing temperature imbalance caused by insufficient local ventilation, and providing basic heat dissipation guarantee for the equipment under different operating conditions.
[0018] Furthermore, a side door 3 is hinged to the outer side of the switch housing 1, sealing off the side of the switch housing 1. A display screen 4 is fixedly installed on the outer side of the side door 3 near the top. The side door 3, which is hinged to the outer side of the switch housing 1, not only facilitates the opening and maintenance of the internal structure by the staff, but also creates a closed space when the switch housing 1 is not under maintenance. This reduces the direct intrusion of external high-temperature airflow, dust and other impurities into the housing, thus protecting the core components such as the switch structure. The display screen 4 on the outer side of the side door 3 displays the equipment temperature and operating status, as well as key parameters such as the speed of the cooling fan 6 and the coolant level in the coolant tank 8 in real time. This allows the staff to have a comprehensive understanding of the working status of each system of the equipment and facilitates the early prediction of potential faults.
[0019] Furthermore, the heat dissipation structure includes a cooling fan mounting slot 5 and a cooling fan 6. A set of symmetrical cooling fan mounting slots 5 are provided on the top of the switch housing 1. The cooling fan mounting slots 5 penetrate through the top of the switch housing 1. The cooling fan 6 is fixedly installed in the cooling fan mounting slots 5. The switch rack 9 is located directly below the cooling fan 6. In addition to fixing the cooling fan 6, the design of the cooling fan mounting slots 5 penetrating through the top of the switch housing 1 can also accurately guide the airflow direction generated by the cooling fan 6, ensuring that the airflow acts perpendicularly on the switch rack 9, minimizing wind power loss. At the same time, the size of the mounting slot matches the cooling fan 6, which can prevent the vibration generated by the fan during operation from being transmitted to other components through the housing, reduce the risk of component loosening due to vibration, and ensure the long-term stable operation of the cooling fan 6.
[0020] Furthermore, the auxiliary structure includes a switch placement platform 10, a heat dissipation trough 11, and support rods 12. The switch rack 9 has longitudinally linearly distributed switch placement platforms 10 on its side, and heat dissipation troughs 11 on its side. The position and number of heat dissipation troughs 11 correspond to those of the switch placement platforms 10, and the heat dissipation troughs 11 penetrate the side wall of the switch rack 9. Multiple sets of laterally linearly distributed support rods 12 are fixedly installed between adjacent heat dissipation troughs 11 on the outside of the switch rack 9. In addition to providing installation positions for the switches 13, the longitudinally linearly distributed design of the switch placement platforms 10 can also maintain a uniform spacing between the switches when multiple switches 13 are running at the same time, providing circulation space for the heat dissipated by the heat dissipation troughs 11 and preventing heat from accumulating between the switches. In addition to fixing the cooling pipes 16 and enhancing the stability of the switch rack 9, the laterally linearly distributed layout of the support rods 12 can also divide the heat emitted by the heat dissipation troughs 11 and guide the heat to flow towards the cooling pipes 16, improving the heat absorption efficiency of the cooling pipes.
[0021] Furthermore, the switch structure includes a switch 13 and connection ports 14. The switch 13 is fixedly installed inside the switch placement platform 10, and multiple sets of horizontally linearly distributed connection ports 14 are opened on the outer wall of the switch 13. In addition to enabling data transmission, the horizontally linear distribution of the connection ports 14 can avoid mutual interference between the plugging and unplugging operations caused by the dense arrangement of the interfaces, making it convenient for staff to connect or disconnect the lines. At the same time, the connection ports 14 are opened on the outer wall of the switch 13, close to the side door 3. When the side door 3 is opened for line maintenance, the staff does not need to go deep into the shell to operate, simplifying the line management process and reducing the contact interference with other components during maintenance.
[0022] Furthermore, the cooling structure includes mounting holes 7, a coolant tank 8, a cooling pipe fixing plate 15, and cooling pipes 16. The coolant tank 8 is fixedly installed at the bottom of the switch housing 1. A set of through mounting holes 7 is provided at the bottom of the switch housing 1. The cooling pipe fixing plate 15 is fixedly connected to the side of the support rod 12. The cooling pipe 16 is fixedly installed on the outside of the cooling pipe fixing plate 15. The bottom of the cooling pipe 16 passes through the mounting holes 7 and enters the coolant tank 8. In addition to allowing the cooling pipe 16 to pass through and enter the coolant tank 8, the mounting holes 7 are designed to fit tightly with the cooling pipe 16, reducing the gap between the cooling pipe and the hole wall. This reduces the possibility of hot air inside the housing spreading to the bottom coolant tank 8 through the mounting holes, preventing the coolant tank 8 from absorbing too much heat from inside the housing and affecting the cooling effect. In addition to fixing the cooling pipe 16, the way the cooling pipe fixing plate 15 is fixedly connected to the side of the support rod 12 allows the cooling pipe 16 to always be in contact with the side of the switch frame 9, maintaining good contact even when the equipment vibrates, ensuring that the cooling pipe can continuously and efficiently absorb the heat of the switch frame 9.
[0023] Structural Description: Switch housing 1: It is the external protective structure of the device. It is hollow inside, with ventilation slots 2 on the side, a hinged side door 3 on the outer side, and a coolant tank 8 fixedly installed at the bottom. It is fixedly connected to the switch frame 9 through a connecting rod, and plays the role of overall protection and support for the internal structure. Ventilation slot 2: It is formed on the side of the switch housing 1, in two sets of longitudinal linear distributions that run through the side wall, and is symmetrically distributed at both ends of the housing side wall to promote air circulation inside and outside the housing and assist in heat dissipation; Side door 3: Hinged to the outer side of the switch housing 1, it can seal the side of the housing. The display screen 4 is fixedly installed on the outer side near the top, which facilitates the inspection and maintenance of the internal structure and protects the core components. Display screen 4: Fixedly installed on the outer side of the side door 3 near the top, used to display parameters such as equipment temperature, operating status, and cooling fan speed 6, so as to facilitate real-time monitoring of equipment status; Cooling fan mounting slot 5: Located on the top of the switch housing 1, it is symmetrically distributed and extends through the top, used to fix and install the cooling fan 6, and can accurately guide the airflow direction generated by the fan. Cooling fan 6: It is fixedly installed in the cooling fan mounting slot 5, directly below the switch rack 9. It accelerates the airflow around the switch rack 9 by exhausting air downwards, which helps to dissipate heat. Mounting holes 7 are located at the bottom of the switch housing 1 and are distributed in a series to allow the cooling pipes 16 to pass through. They fit tightly with the cooling pipes 16 to reduce the diffusion of hot air inside the housing. Coolant tank 8: Fixedly installed at the bottom of the switch housing 1, it contains coolant and exchanges heat with the switch rack 9 through the cooling pipe 16 to assist in cooling; Switch rack 9: It is fixedly connected to the bottom of the hollow interior of the switch housing 1 by a connecting rod, and has a switch placement platform 10 and a heat dissipation slot 11 on the side for installing the switch structure. Switch placement platform 10: Located on the side of switch rack 9, it is arranged in a longitudinal linear pattern and is used to fix and install switch 13, so that the switch structure is orderly divided. Heat dissipation slot 11: It is located on the side of the switch rack 9, corresponding to the position and number of the switch placement platform 10 and penetrating the side wall, and is used to dissipate the heat generated by the switch 13. Support rod 12: It is fixedly installed between adjacent heat dissipation slots 11 on the outside of the switch rack 9, and is arranged in multiple sets of horizontal linear distribution to enhance the stability of the frame and provide a fixed support for the cooling pipe 16; Switch 13: Fixedly installed inside the switch platform 10, with a connection port 14 on the outer wall facing outwards, it is the core component for realizing data transmission and device interconnection; Connection port 14: Located on the outer wall of the switch 13, it is arranged in multiple groups in a horizontal linear distribution and is used for data transmission and line connection, which facilitates maintenance and operation; Cooling pipe fixing plate 15: It is fixedly connected to the side of the support rod 12, and the cooling pipe 16 is fixedly installed on the outside to ensure that the cooling pipe 16 is always in contact with the switch frame 9; Cooling pipe 16: It is fixedly installed on the outside of the cooling pipe fixing plate 15, and its bottom passes through the mounting hole 7 and enters the coolant tank 8. It conducts the heat of the exchange frame 9 through the internal coolant circulation. Working Principle: When the switch 13 operates in an industrial environment, the heat it generates is first dissipated directly through the heat dissipation trough 11 in the auxiliary structure. Since the heat dissipation trough 11 corresponds to the position of the switch mounting platform 10, it can accurately absorb the heat of the switch 13 and diffuse it to the surroundings. At the same time, the cooling fan 6 in the top heat dissipation structure starts, exhausting air downwards through the cooling fan mounting slot 5. The airflow directly acts on the switch rack 9, accelerating the airflow around the switch rack 9 and pushing the heat dissipated by the heat dissipation trough 11 upwards. The ventilation slot 2 on the side of the switch shell 1 forms convection with the cooling fan 6 on the top. External cold air enters the shell from the ventilation slot 2, mixes with the hot air, and is then exhausted by the cooling fan 6, realizing the circulation and renewal of the air inside the shell and continuously removing heat. The cooling structure and the auxiliary structure are fixedly connected by the support rod 12 and the cooling pipe fixing plate 15, so that the cooling pipe 16 is in close contact with the outside of the switch rack 9. When the temperature of the switch rack 9 rises, the coolant in the cooling pipe 16 absorbs heat and conducts the heat to the coolant tank 8 through the mounting hole 7 at the bottom. After heat exchange within the coolant tank 8, the coolant circulates back, forming a continuous liquid cooling channel. This, combined with the air-cooling system, creates dual heat dissipation. The support rod 12, while fixing the cooling pipe 16, enhances the stability of the switch frame 9, preventing the cooling pipe 16 from detaching from the switch frame 9 due to equipment vibration, thus ensuring that the liquid cooling effect is not affected. Real-time data generated during the operation of the switch 13 is transmitted to the control system via the connection port 14. The display screen 4 on the side door 3 simultaneously displays parameters such as the equipment's temperature and operating status. Staff can monitor the equipment status in real time via the display screen 4. If any abnormality occurs, the side door 3 can be opened directly for maintenance without disassembling the outer casing, which is convenient for operation and reduces downtime caused by maintenance. The longitudinally linearly distributed switch placement platform 10 arranges multiple switches 13 in an orderly manner, avoiding heat accumulation caused by the dense arrangement of traditional equipment components. The heat generated by each switch 13 is independently dissipated through its corresponding heat dissipation slot 11, and then centrally processed by the cooling fan 6 and cooling pipe 16, significantly reducing thermal interference between components.
